RESILIENT WHEEL.

Application led January 31, 1927. Serial No. 164,961.

This invention relates to certain novel improvements in resilient wheelsand has l'or its principal object the provision oi an improvedconstruction ot this character which will be highly e'liicient in useand economical in manufacture.

Among the several objects ol the invention is the provision ot a springwheel which has associated therewith the usual rubber 'io tire andmounted in this tire in lieu of the ordinary pneumatic tube iscushioning mechanism thereby eliminating punctures which frequentlyhappen with the ordinary pneumatic tire.

A. still further object of the invention is the provision vof aresilient Wheel having cushioning` mechanism selectively arranged inassembled position for expeditious insertion in the ordinary rubber tirecarried by an the telly rim.

A still vfurther object of the invention is the provision of a rubbertire having cushioning means arranged therein in lieu of the ordinarypneumatic tube With means for im properly adjusting the cushioning meanscircumferentially about the telly of the Wheel.

Other objects Will appear hereinafter. The invention consists in thenovel combitu nation and arrangement of parts to be heieinatterdescribed and claimed.

The invention Will be best understood by reference to the accompanyingdrawings, showing the preferred forni of construction im and in Which:

Fig. 1 is a vertical sectional detail view of the invention;

Fig. 2 is a sectional detail view taken sub stantially on line 2-2 ofFig. 1;

Fig. 3 is a fragmentary plan View taken substantially on line 3?) ofFig. 1.

As hereintotore indicated, it is an object ot the invention to provide acushioning means for a vehicle Wheel to take the place l5 of theordinary pneumatic tube whereby to avoid the frequent trouble suoli aspunctures and blow-outs as occur to a vehicle Wheel having the pneumatictube associated there with. To accompli-sli this and other objects toont the invention l associate Vmy cushioning means with the ordinarystandard tire 10. This tire is connected in a Well-known manner to a rim11 mounted circumferen tially about the ielly 12 ot a Wheel 13 havingthe usual spokes 14. Formed in the telly 12 at opposite diametricalpoints are lli radially extending openings 15 which regis-- ter Withopenings 16 formed in bosses 1'?, said openings 16 being threaded forreasons hereinafter set forth.

The cushioning means embodying my in vention comprises a plurality orS-sliaped springs 1S having corresponding end portions 19 secured to theouter ring 20 which is split as at 21. Arranged between the convolutionsoit the springs 1S are ani:n lhary springs 22. The end convolutions Q3of these auxiliary springs 2Q ein brace studs 2li secured to the springs18, said studs 24 functioning to retain the auxiliary springs 22 inproper relation. The opposite corresponding end portions 25` of thesprings 18 are secured to an intermediate ring 26 split as at 2T. Thisinterinediate -ring is concaved in. cross-section and arranged in theconcaved portion is a coin-y pressible ring 28. This coinpressible ring28 is supported circumgterentially about an inner ring 29. Extendingradially and in- Wardly from the inner ring 29 are a plurality oadjusting bolts 30. The outer end portions 31 of these bolts arearranged in abutment With an inner ring 29 as best shown in Fig. 2.

The bolts have threaded portions 32 which are adapted to mesh. with thethreads ol the opening 16. The inner end portions olthese bolts projectinwardly through the openings 15 and formed on their extremities arel'lat heads 83 upon which is adapted to be manipulated a suitable tool(not shown) 'tor adjusting the adjusting bolts relative to the telly 10.

The inner ring 29 has its opposite end portions 34C slidably connectedtogether through the medium ot a tongue and groove connection 35.

In use the cushioning mechanism is ar ranged in the tire l() and afterthis has been accomplished the bolts 3() are adjusted to properly setthe springs and their respective rings in proper position to give thedesired resiliency to the tire l0.

It vvill be manifest that When the tire is tractioned the springsembodying the invention vvill act to keep the tire in its properinflated condition 'While at the same time permit suliicient compressionwhen the tire is tractioned over an uneven road.

By providing the rings 2G and 9.9 ot the split type it will be manifestthat insertion and removal ol the cushioning mechanism (lll Uli

till

from the tire 10 may be expeditiously accomplished. v Y

It Will be seen from the description. herein that the. tire to beinflated does not require aie1 and that the inflated condition of thetire is maintained through the medium of the spring members embodyingthe invention. l

While I have illustrated and described the preferred form otIconstruction for carryvingmy invent-ion into effect, this is capable ofvariation and modification, without departing from the spirit ot theinvention. l, therefor@ do not wish to be limited to the precise detailsof construction set torth, but desire to avail myseltl ofsuch variationsand modications as come Within the scope of the! appended claims.

Having thus described' my invention wha I claim as new and desire toprotect by Letters Patent is:

1. The combination with a fellyfot a vehicle wheel, a tire rim mountedon the telly and a tire carried by the tire rim, of enshioning mechanismarranged within the tire`r and means carried by the tire rim and oper lable on the cushioning mechanism for adjusting said cushioning mechanismradially with respect to the tire, said cushioning mechanism includingtwo concentrically spaced ring members, S shaped spring members disposedtransversely*betweenl and havi ing their opposite end portions connectedto said rings, and auxiliary spring members extendingradially betweenand abutting the convolutions of said S shaped spring members.

Y 2. The combination with a felly of a vehicle Wheel, a tire rim mountedon the telly and a tire carried by the tire rim, ot cushioning mechanismarranged within the tire, means carried by the tire rim and operable onthe cushioning mechanism for adjusting said cushioning mechanismradially with respect to the tire, said cushioning nieehanism includingtwo concentrically spaced split ring members, S shaped spring membersdisposed transversely between and having their opposite end portionsconnected to said rings, and auxiliary spring members extending radiallybetween and abuttingl the conyolntions ot said S shaped spring members.

3. The combination with a 'l'elly ot a vehicle wheel7 a tire rim mountedon the telly and a. tire carried by the tire rim, ot enshioningmechanism arranged within the tire, means carried by the tire rim andoperable on the cushioning mechanism tor adjusting said cushioningmechanism radially with respect to the tire, said cushioning mechanismincluding two concentrici'illy spared ring members, S shaped .springmembers disposed transversely between and having their opposite endportions connected to said rings, auxiliary spring members eritendinglradially between and abuttingl the convolutions ot said S shaped springmembers. an inner split ring` member arranged concentrieally withrespect to one. ot said tirst mentioned ring-meml'iers and having itsend portions slidalilyv connected together, and a compressible memberarranged betwewi said inner ring member and said one ot the firstmentioned ring menibers.
